as above. Can you please share? thanks in advance.
PS. I've seen some non-inverting PCBs in aliexpress and it seems to me that it's possible (relatively easy) to turn these into inverting?

You could always create your own. I highly recommend KiCAD for the schematic and PCB layout: https://www.kicad.org
I give a lot of tips and tricks regarding the LM3886 here: https://neurochrome.com/pages/taming-the-lm3886-chip-amplifier
Your main obstacle these days will be the availability of the LM3886. Due to the chip shortage, most distributors report a lead time around nine months right now. That said, TI does occasionally make a few handfuls available on their website.

Its not about converting it to inverting, but you can go through for mods, especially about cutting grounding traces when used in these PCBs are used in pairs for stereo.
For your application, too many traces will be needed to cut or rerouted. I suggest, grab a few LM3886 first, then you can go P2P, breadboard or purchase / fab your own PCB

Bob Cordell's Super Gainclone may be an option as well. I measured the performance of one implementation of it: https://neurochrome.com/pages/super-gainclone-with-klever-klipper
